How Dimensionally Stable Anodes (DSA) are Used for Hydrogen Production? Hydrogen production via electrochemical technology is one of the most sustainable methods, choosing an appropriate counter electrode is critical. Modified electrodes of dimensionally stable anodes (DSA) have emerged as an alternative, with a high chemical and electrochemical stability. The chosen coating must allow the transport of an electric charge between the base metal and the electrode/electrolyte interface, as well as being able to catalyse the electro

What Anode Material is Used for Organic Impurities Removal? Removal of organic impurities in industrial wastewaters, especially those containing phenol and chlorophenols is very important for environmental protection. Electrooxidation of these impurities appears to be a promising process since no additional oxidative reagents should be used. An appropriate anode material with good electrocatalytic activity for the oxidation organic compound is significant. The oxidation of phenol and substituted phenols has been investigated

How Dimensionally Stable Anodes(DSA) are Applied for the Chlor-alkali Industry? During the first half of the 20th century, Chlor-alkali cells were equipped with graphite anodes. Despite having been a well established technology for the anodic evolution of chlorine, the disadvantages related to the consumption of graphite were evident. The oxidation of graphite, not only caused the contamination of the chlorine but also reduced the service life of the anodes to a maximum of 24 months. Besides, the consumption of graphite increases t

What is Oxygen Evolution Reaction(OER)? The oxygen evolution reaction (OER) takes place in many industrial processes, such as water electrolysis, electrowinning, cathodic protection and electro-organic synthesis. Unlike hydrogen and chlorine evolution on metals or metal oxides, the OER represents low reversibility. Understanding the complicated kinetics of the OER presents a challenge to electrochemists. Metal oxides are most frequently used as anodes in acidic media, although most transition metal oxides such as nickel, cobalt and
